Skylab was the first space station of the United States. NASA carried out three manned missions to Skylab in 1973 and 1974. To commemorate those missions, the Franklin Mint produced medals at the time called eyewitness medals. The silver versions and even the platinum versions of these medals can be found fairly often, but the gold versions are extremely scarce. It is likely that many of the original gold medals were melted and sold over the years with the increase in gold prices. This is a complete set of all three medals from each of the three missions (9 medals total) of the Skylab program. The medals are housed in a custom made Capital plastics holder. Each of the gold medals is actually a pendant that can be worn as jewelry and are made of 18 karat gold and is marked on the edge as such. The 18K gold medals each weigh approximately 15.5 grams. The platinum medals each weight approximately 1.3 grams and are made of pure platinum. The sterling silver medals each weigh approximately 25.6 grams each. The medals are in excellent condition and are quite attractive. A rare opportunity to obtain the complete collection of Skylab Eyewitness medals in a great custom holder.
